The plastic frame 300 is disposed between the transflective layer 130 of the display structure layer 100 and the transparent electrode layer 250 of the rearview mirror structure layer 200. The plastic frame 300, the transflective layer 130 and the transparent electrode layer 250 define an accommodating space S. The electrochromic material 310 is filled in the accommodating space S.
The rear view mirror 10a of the present embodiment is formed by fixing the display structure layer 100 and the rear view mirror structure layer 200 together through the rubber frame 300, that is, the rear view mirror 10a of the present embodiment is embodied as a two-layer structure. As shown in fig. 1J. The periphery of the mirror structure layer 200 of the present embodiment protrudes by a distance G1 with respect to the periphery of the display structure layer 100. That is, the size of the rearview mirror structure layer 200 of the present embodiment is larger than the size of the display structure layer 100, but not limited thereto. In addition, in an embodiment, the surface shape of the rearview mirror 10a is, for example, a circle, an ellipse or a polygon. In another embodiment, the visible surface of the second transparent substrate 210 is, for example, a plane or a curved surface. In another embodiment, the visible surface area of the second transparent substrate 210 may be a full mirror, for example.
Since the annular shielding layer 220 and the touch sensing layer 230 in the rearview mirror structure 200 of the present embodiment are both disposed on the second transparent substrate 210, and the annular shielding layer 220 and the touch sensing layer 230 are electrically insulated. That is, the annular shielding layer 220 is a non-transparent non-conductive material as a shielding ring, and is directly integrated with the touch sensing layer 230 on the same transparent substrate. Therefore, the rearview mirror 10a of the present embodiment has a touch function in addition to the display function of the full screen, and the thickness and weight of the whole rearview mirror can be effectively reduced. When the driver uses the rearview mirror 10a, the driver can directly touch the rearview mirror, and the rearview mirror has better use sensitivity, easy operation and beautiful appearance. In addition, the display structure layer 100 of the rear view mirror 10a of the present embodiment also integrates the display body layer 110 and the transflective layer 130 on the first transparent substrate 120, so as to effectively reduce the weight and thickness of the rear view mirror 10 a.
